Saddle Fusion Process

The key steps involved in saddle fusion are:

1. Preparation

Before starting the saddle fusion process, it’s essential to thoroughly clean and prepare the pipe and fitting surfaces. Any dirt, debris, or contaminants should be removed to ensure a clean fusion.

2. Clamping

Securely clamp the saddle fusion machine onto the pipe, then secure the saddle fitting into the machine. The clamps hold the components in place during the fusion process, ensuring they do not move or misalign.

3. Marking and Alignment

Mark the position where the saddle fitting will be attached to the main pipe. Proper alignment is crucial for a successful fusion, so take care to align the fitting accurately.

4. Heating

Use a specialized heating tool to heat the surfaces of both the main pipe and the saddle fitting. The heating tool typically includes heating plates or a heating element that is placed against the surfaces to be fused.

5. Heating Time

Allow sufficient time for the heating process. The duration will depend on factors such as the type and thickness of the thermoplastic material. It is crucial to follow the manufacturer’s guidelines for the specific materials being fused.

6. Cooling

Once the heating is complete, remove the heater and apply proper fusion force, per manufacturer’s recommendations, and allow the fused joint to cool. Cooling times can vary, and it’s important not to disturb the joint during this phase to ensure proper solidification of the melted thermoplastic material.

7. Inspection

After the joint has cooled, inspect the joint visually to ensure there are no irregularities, and that the fusion is uniform and without any visible defects. The fusion bead should have a characteristic “three-bead” shape. 

8. Testing

Conduct pressure tests or other relevant quality checks to verify the integrity of the saddle fusion joint. This step is crucial to ensure that the joint is leak-resistant and meets the required performance standards.

9. Documentation

Maintain detailed documentation of the saddle fusion process, including the fusion parameters, cooling times, and any quality control tests performed. Proper documentation is essential for quality assurance and compliance.
